VEHIQLE DOOR FiledJurie 9, 1937 2 Sheets-Sheet 1 Patented Apr. 1, 1941 VEHICLE DOOR Lon Mollet, Asnieres, France, assignor to Societe Anonyme des Usines Chausson, Asmeres, Seine,

France Applicatien June 9, 1937, Srial N0. 147,344 In France June 17, 1936 1 Claim The metallic doors for motor vehcles and the lik-e consist essentially of two pressed panels forming the inner and outer aces of the door. In the usual methods of construction, these panels are joined together by foldng the edge of the outer panel about the edge of the inner panel by means of a pneumatic hammer. The door thus has a thin edge, upon which it is not an easy matter to mount a packing.

On the other hand, the wndow opening of the door is borderecl directly by the edges of the corresponding openings ormed in the two panels and thus the said edges -cannot remain in the rough state after punching, and must be bent over towards the inside wh.ile leaving a passage for the glass pane, thus requiring additional operations which greatly increase the cost price of the door.

One object of the present invention is to provide a new metallic door construction for motor vehcles and the like, in which the edge portions of the inner and the outer pressed panels are placed in contact and joined together by spot welding for example, and are then bent at an angle upon the whole or a part of the periphery of the door in order to form a peripheral channel groove adapted to receive a packing band.

Accorclng to a urther feature of the invention, the edges of the openings in the inner and outer pressed panels, which serve to form the window, rernan in the rough state as they are left after the punching process, and a channel bar is secured between the upper edges and between the lateral edges of the two panels, and to the lower edge of both panels are secured flat bars leaving between them a space for the passage of the glass pane, the said channel bars and the flat bars being provided with section pieces of rubber or the like, f or packing purposes.

In the accompanying drawings, which are gven solely by way of example:

Fig. 1 is a vertical longitudinal section, of a very diagrammatic nature, showing the two inner and outer pressed panels of the door which are simply placed together, before joining.

Fig. 2 is a like view, with the two members joined together.

Fig. 3 is a partial secton on a larger scala, after the assembling, on the line 3-3 of Fg. 6.

Fig. 4 is a perspective view of the outer pressed panel alone, said panel being shown with the flange such as it is formed after having been secured. to the inner pressed panel.

Fig. 5. is a perspective view showing the channel bar and the two flat bars employed for the window.

Fig. 6 is a perspective view showng the metallic assemblage forming the door, but freed from i'ts various furnitures and its peripheral packing band.

In the embodiment herein represented, the door consists essentally of a pressed. metallic panel l which is adapted to form the outer face of the door, and of -a second pressed panel 2 which is adapted to form its inner face.

The said panels 1 and 2 comprise, upon their entire periphery, edge portions 3 and 4 (Fig'. 1) having the same width, this being greater than that of the edges of the pressed panels in current use. The edges 3 and 4 are such that they wll fit exactly upon each other, as shown in Fig. 1. The two pressed panels are joined together by a sutable number of electric welding spots between the edges 3 and 4, af-ter which these edges are bent at an angle, as shown in Figs. 2, 3 and 6. For this purpose, use is made of any suitable press, in such way that the operation is effected by a single movement, without any danger of distortion, as is the case with the usual construction, in which the edge of the outer pressed panel is folded about the eclge which is less wide, of the inner pressed panel, at successive points by means of a pneumato hammer.

Alter this operation, the door has a groove in i-ts inner face, around the whole periphery, and in this groove is placed a band 5 (Figs. 2 and 3) of rubber or like material, which is adapted to form a packing member when applied aganst the door frame.

In each of the two pressed panels is in an opening adapted to form the window part, but whereas in the usual doors, the edges 61 of such openings are bent down, in the present case they are preserved just as they are left after the pressing process, being thus parallel with the two pressed panels. Between these eclges 6-! is mounted a channel bar 8 which surrounds the window on the upper scle and the two lateral sides.

On the lower side of the winlow, the secti-on piece 8 is replaced by two fiat bars 9-l0 which are seoured. respectvely -to the outer pressed panel I and to the inner pressed panel 2. Between these two bars 9-!!! is a passage for the glass pane I l (Fig. 3). The channel bar 8 and the bars 9-l0 are respectively provided with a packing member |2 and with packing members I3 and. 14 (Fig. 3), cunsisting of rubber or like material. Use is also made =of auxliary packing members l5, of felt or the like.

The a-ssembling of the parts of the wndow 01ers no dfiiculty; the channel bar 8 and the bars 9i are secured by welclng to one of the pressed panels, for nstance the inner pressed panel 2, before it is joined to the other pressed panel, and after the two panels 1 and 2 have been jolned tcgether, they are weldecl to the other panel.

As will =be observed the nventon permts of obtaning, in partcularly simple condtions, a door of a most resstant nature, without dstorton, ancl provclng for a very tght fi1, between the door and ts frame.

Obviously, the nventon is not limited to the embodment heren descrbed and represented,

whch is gven solely by way of example.

Havng now descrbecl my nvention what I claim as new and desre to secure by Letters Patent is:

In a metallic vehcle wndow constructon an outer panel and =an nner panel, both havng registerng openings theren, the margins of the two openngs being spaced fr-om each other as 1:0 afford room for a wndow pane, fianges formed on LON MOLLET.
